How To Choose

Know What You Want From Your Napa County Window Contractor

You can improve the comfort, appearance and value of your home all at once by investing in new windows. But your windows are only as good as the Napa County window contractor you choose to install them. Research is the key to finding the best window contractors in Napa County, including those in the major cities of Napa, American Canyon, St. Helena, Calistoga and Yountville, as well as those in the smaller towns and rural areas.

Whether you want to invest in beautiful and efficient windows that immediately increase your home's value, trade in your drafty windows for lower heating and cooling bills or swap those small windows with peeling frames for an improved view and aesthetic, the first step in hiring window contractor is deciding what you want to get from your new windows. By having a specific goal, you're more likely to find the Napa County window contractor that best meets your needs.

The Clear Choice for Commercial Window Installation in Napa County
Show-stopping storefronts and aesthetically-appealing commercial buildings in larger Napa County cities such as Napa, Yountville, St. Helena, American Canyon and Calistoga, and some of the smaller cities, have one obvious element in common -windows that are visually pleasing to the public and that make working and shopping inside more enjoyable.

But selecting and installing new windows for commercial buildings and stores is a different process than for residential windows. Commercial window materials are often stronger and more flexible, which allows for eye-catching design and building stability. Commercial window products range from opaque reflective surfaces and shatter-proof safety glass to windows built for security.

While most window contractors in Napa County can sell and install windows for commercial buildings and storefronts, some contractors do more of this type of work than others. So choose commercial window contractors that have the skills and knowledge to help you make the best decision for your project. Factors to consider when choosing commercial windows include:

When you've found experienced commercial window contractors that will help you consider all the important factors for your store or office window installation, follow the same steps for residential window installation to be sure you're hiring the best company for the job.

The Value of Researching Your Window Installation Choices
Every Napa County window company says they're the best. So how do you see through the self-promotion and find the window contractors with proven records?

While it's usually best to choose a Diamond Certified company that's rated Highest in Quality, it may not always be possible. If you're unable to choose a Diamond Certified window contractor in your area of Napa County, it's wise to check out candidates on the Contractors State License Board website. Here, you can to ensure they have an active license and workers' compensation insurance. Any violations they've been convicted of or serious customer grievances will also appear on that website. Also take time to verify company credentials. For instance, some local window contractors are authorized distributors who can simplify the entire process for you because they serve as official installers for various window manufacturers.

Installing new windows or replacement windows can be a big job, so you may be spending days, weeks or even months dealing with your contractor. Like with any working relationship, it's important that you work well as a team. You'll want to consider the professional qualities you prize in a window installer. Additionally, personal traits such as promptness, strong communication skills, honesty and cleanliness are important to many consumers.

Some window installation companies in Napa County, including in the larger cities of Napa, St. Helena, Calistoga, Angwin, Yountville and American Canyon have salespersons who sell windows but aren't involved in the installation. If that's the case with your window contractor, it's possible that the rapport you've built and the agreements you've made with your salesperson might not carry through to the rest of the job. When talking with local window sales representatives, you may want to confirm with them who will be your contact during the installation and how they can guarantee the promises made during the sales process will be kept by the installation crew before you sign a contract.

Further Research on Window Contractors inThese Major Napa County Cities: Napa, American Canyon, St. Helena, Calistoga and Yountville
Now that you have a short list of good window contractors, talk with a few in your area. That's easy if you live in one of the larger cities, including Napa, St. Helena, American Canyon, Calistoga or Yountville. And luckily, many window installers are willing to travel to more rural parts of Napa County, including the smaller towns of Angwin, Deer Park, Pope Valley, Oakville and Rutherford.

When you interview window company owners, have a written list of questions (see the section, Thoroughly Interview Qualified Window Installers) and note the answers the contractors give you. Don't be surprised if most of the window installation contractors you talk to want to see the job before giving you an estimate for your new windows. However, you shouldn't feel obligated to get an in-home estimate if you weren't impressed with your initial contact with a company. If the window installers you've talked with don't meet your expectations or can't answer your questions, end the conversation and move on to the next name on your list.

Know What You Want

Determine Your Expectations for Your New Windows

Start the process by asking yourself some questions to get a clear scope of your project. You’ll want to know the type of windows you prefer and what you’re looking for in a contractor, too. Most homeowners find that before they interview local window contractors in Napa County, it helps to write down ideas and questions so they can present a clearer case to the contractors they interview. To get started, ask yourself these questions:

Do I plan to live in this home long-term, or is it a rental property or house I plan to sell in the near future?

What characteristics do I most want in a Napa County window contractor? (This could include communication skills, timeliness, certain experience, honesty, specific warranties or guarantees, and follow-up service.)

What To Ask References

Benefit From Previous Customers' Experiences with Local Window Contractors in Napa County, Including the Smaller Cities of Angwin, Pope Valley, Rutherford, Deer Park and Oakville

It’s best to choose a Diamond Certified window contractor because all certified companies have passed an in-depth ratings process that few other companies can pass. If you want quality from a window company in Napa County and the greater Bay Area, you’ll be confident choosing a Diamond Certified company. Free reports are available online for all certified companies. And you’ll never be fooled by fake reviews because all research is performed in live telephone interviews of actual customers.

If you can’t find a Diamond Certified window contractor within reach, you’ll have to research some local window companies on your own. In that case, it’s wise to call some references provided by the best window companies you can find. Remember, though, those references are not equal in value to the large random sample of customers surveyed during the Diamond Certified process. That’s because companies usually give selected references to potential customers, instead of giving names randomly selected from their entire customer base. So there’s no way to tell if you’re getting a fair sampling of customer reactions and references. If you do call references on your own, ask for a list of each company’s most recent customers. This will help avoid them giving you the names of customers they know were satisfied.

Talking to references can give you an insider’s view on how the Napa County window contractors have performed on previous jobs. So call several references and ask them specific questions about the contractor. Here are some sample questions to help you:

Were you satisfied with the window installation and the service from _(Napa County window company name)_?

If you need new windows in the future, would you use this window contractor again?

What was the type and scope of job they did for you (window repair, window replacement, whole house window installation, vinyl window installation, etc.)?

Did the contractor keep you up-to-date on the status of the project?

Did the Napa County window contractor you hired complete the work on time?

Were there unexpected costs? If so, what were they?

If you live in a smaller town such as Oakville, Pope Valley, Rutherford, Angwin or Deer Park, did they charge extra to travel to your home?

The Diamond Certified symbol has been awarded to companies that scored Highest in Quality in an accurate ratings process.

Your choice of window contractor impacts every aspect of your job, from the choice of materials and ease of the installation to how long your new windows last. So it's important to consider the following questions before deciding on the best window contractor in Napa County for you.

Can the Napa window contractors meet your needs in terms of scheduling, products and installation preferences?

Is the window installation company sensitive to your budget? Did they offer various products and services to better fit your resources? (Most contractors will give you bids for Good, Better and Best options that include a choice of product, design, prices, brand names and services.)

Do the window contractors in Napa offer warranties that cover product failures or installation errors?

Will they put all guarantees in writing?

Additionally, note your own expectations, and remember that some may not be congruous with the project. For example, it may not be realistic to expect a quiet worksite, consistent schedule or immediate results when getting new windows installed. You're most likely to be satisfied when you talk with the contractor before the job begins to discuss realities and expectations from both of your points of view.

How To Work With

How to Get the Best Local Window Installers in Napa County to Bid on Your Job

In this buyer’s market, you might be surprised to find you’re not the only one who is interviewing and selecting potential candidates. Napa County window companies, including those in the larger cities of St. Helena, Yountville, American Canyon, Napa and Calistoga and even some in the smaller towns, can also be selective about which jobs they accept. Bids take time and expense to prepare, and many contractors have lost money and faced difficult dealings with unreasonable homeowners. That can make them choosy about with whom they do business. So it’s reasonable that some local window contractors show a lack of interest or don’t respond to all job requests.

There are some ways you can encourage good window contractors to bid on your job.

Shop among local window contractors in Napa County. Most like to stay in the Napa area, as it allows them to provide better service in a timely fashion. It also shows that you’re serious about quality products and lasting installations, as some fly-by-night contractors from out of the area travel long distances and install cheap products that honest local contractors may not be able to compete with price-wise.

Be honest about the fact that you’re accepting other bids and interviewing other window contractors, but assure them you’re gathering three bids, not dozens.

Look for good value, not just the lowest price. The first question that contractors often hear is about price, so it’s important to show them you understand the importance of quality and overall value.

Get the Most Out of Your Deal with Napa Window CompaniesCongratulations! You’ve finally found the perfect window contractor that meets all your requirements. Now is the time to ask for a written contract that confirms the price, quality and schedule for the whole job. The Napa County window installers should also be willing to provide you with a written timeline that covers the job start date, major milestones and intended completion date along with areas of specific concern.

The contract you sign with a Napa County window company should protect you and your property as well as your contractor’s interests. For this reason, never sign a blank or incomplete estimate. Read and understand the entire contract before you sign it. You should also be able to write in special requests or verbal agreements you and your representative have made.

For example, project start and end dates are important, but some factors, such as weather, you nor your installer can control may interrupt and hold up the job. That’s why it’s a smart idea to add a no-later-than clause to your contract. This stipulates the date by which all work must be completed. Even if inclement weather or problems with the products delay installation, this clause will give you assurance that your job will be finished on time. If a quick turnaround is important to you, you may want to consider adding a bonus for early completion to your contract as well.

Confirm any warrantees at this time, as some window installers in Napa County only guarantee certain brands or installation techniques. Also verify that manufacturer warrantees apply to the windows you’re having installed.

Don’t forget about related issues that may not be covered by standard contracts. For example, no matter how careful your window installer is, crushed plants, damaged shrubs and rutted lawns are often unexpected hazards that come with hiring a contractor. But some proactive planning can protect your property. Ask the job supervisor to accompany you on a pre-work inspection of the condition of your property. List and/or photograph landscaping and the exterior of your home before the work begins, and ask your contractor about reasonable expectations for protecting your home and yard during the installation process. When you’ve reached an agreement, you and the contractor should sign and date the document. After the work is done, do a final inspection together to confirm your expectations were met.

Be a Good Customer

How Can You Be a Good Window Company

It’s the window company’s responsibility install quality windows using the best possible techniques. But you also can play a big part in the success of the work. Here are a few simple steps you can take to be a good customer when hiring a Napa County window contractor.

Before you hire a window contractor in Napa County, restate your expectations and goals. Most problems with local window contractors occur because of a breakdown in communication. So reiterate your understanding of the agreement to the window company representative. By being clear about your expectations and theirs, you can avoid most conflicts.

Be clear and upfront with your window contractor. Explain what you want from your windows, the long-term results you’re expecting and specific ways they can keep you happy.

Remember, a friendly smile goes a long way!

Ask your window installer if you should call to check on the progress or if he will call you with updates. If he promises to call with updates, set a standard for how often you expect to hear from him to avoid disappointment or miscommunication.

Be sure your service representative has your phone number and can reach you at all times. The work can move along more smoothly if your window company can reach you for any necessary updates, questions or work authorizations.

Why would you want to be a good customer? Window installation contractors in Napa County appreciate customers who are straightforward, honest and easy to work with. Your good customer behavior sets the tone from your end and creates an environment conducive to a good relationship. Things may also go smoother and any problems may be more easily resolved.

Check The Work

Check the Written Invoice Against the Completed Window Installation

Good window contractors in Napa County will give you a written invoice that usually includes:

The window contractor's name and physical address.

The total window installation cost, including the amount charged for labor.

A list of all work performed.

An itemized record of all new windowsor window replacement parts.

Any applicable guarantees or warrantees provided by the window manufacturers or the window installers.

Ask your window company representative to walk through the job with you so that you can compare the written invoice to the work that was actually done. He or she should give you instructions for operating your new windows and maintaining them for years to come. If you have questions about the work or the installation, this is the time to ask.

Written Warranties

Ask Your Napa County Window Installers for Written Warranties

Before your window contractors leave the jobsite, confirm any warranties. Not all window companies in Napa County back up their work. But if the shop you've chosen does, they should give you a written warranty that specifies:

The window contractor's name, license number and physical address.

Warranty terms, limitations and exclusions, including whether the contractor will replace or repair your windows or give you a refund if there is a warranty claim.

Your responsibility if you require warranty work or replacement windows (i.e., if you have to pay for labor when filing a claim for windowwarranty work or pay a prorated amount).

Terms of and limitations on the new window warranty.

If the new window warranty coverage is transferrable to the new owner if you sell your home.

Double hung windows are often available as energy efficient windows, so despite their large surface area, they are generally very efficient.

Bay Windows / Bow Windows
Bay windows (also known as bow windows) are popular requests in Napa County because they project outward from the main walls of a home. This creates a larger living space or the illusion of a larger room depending on the type of bay window installed. Bay windows and bow windows also add architectural interest and increase the amount of natural light that enters a room.

Aluminum Windows
Known as strong, durable and easy-to-configure, aluminum windows are often used to showcase beautiful views. They are also a less-expensive option in homes and light commercial buildings.

insulating glass
Insulated glass is usually a combination of two or more panes of glass with a sealed air space between the panes that is filled with a harmless gas. This space may be filled with an inert gas, which increases the insulation properties. Most major window companies offer insulated windows as part of their standard catalog.

picture windows
Non-venting and non-operable windows are generally referred to as picture windows. Also know as fixed windows, picture windows only consist of window frames and glass. Most picture windows are double-paned or insulated to be more energy efficient since they have such a large surface area.

storm windows
Mounted outside or inside the main glass, storm windows are often found in cold climates or as a retrofit of existing windows. Storm windows increase the efficiency of glass windows and can be mounted temporarily or permanently.

window cladding
Cladding is material applied to the outside faces of windows to provide a durable, low-maintenance exterior surface. Cladding often provides protection from the elements and adds an aesthetic touch. It may also be referred to as window capping, which is a specialized field offered by few window contractors.

Also known as: cladded windows, clad windows, vinyl-clad windows

window sash
Window sashes are single frame assemblies of stiles and rails (explain stiles and rails) that hold the glass.

wood windows
Wood windows are those with wooden frames. They are a natural option, so they require more maintenance than vinyl windows, and they must be protected from moisture to avoid warping and rot.

Frequently Asked Questions

Frequently Asked Questions for Local Window Contractors

Q: Why choose a Diamond Certified Window Company?
A: Diamond Certified ends the guessing game by helping you choose a window contractor with confidence by offering a list of top-rated local companies who have passed the country’s most in-depth rating process. Only window companies rated Highest in Quality earn the prestigious Diamond Certified award. Most local window companies can’t pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with in-depth and ongoing research and ratings. And your window installation purchase is backed by the Diamond Certified Performance Guarantee. So you’ll feel confident choosing a Diamond Certified window company for your new windows.

Q: How will replacing my windows improve the comfort of my home?
A: New windows will make your home quieter and more secure. Depending on the windows you choose, you may also notice a marked difference in the temperature of your home as well. Double-paned windows are insulated to keep out the heat of the summer, and maintain heat during the winter.

Q: Will replacing my old windows save me money?
A: Old windows and windows that are improperly installed are the biggest cause of energy loss in the home, costing you money every day. New windows will save you money over the life of the window by cutting heating and cooling costs. Some homeowners report savings of up to 30 percent on their utility bills after installing new windows. New windows can also increase the life of your furnishings and carpeting by keeping out harmful rays of the sun, so you’ll save money by not having to replace expensive furnishings.

Q: If I decide to sell my home, will new windows and doors increase the value?
A: Yes. New windows are one of the best home improvements you can make in terms of the return on your investment. Realtors report that Bay Area homes with new energy-efficient, maintenance-free windows can see return of up to 114% in resale value.

Q: What window materials do I have to choose from?
A: Your choices for new windows are wood, vinyl, steel, aluminum, fiberglass and composite. You’ll see the sash and the frame (the visible outer parts of the window installation units) from the inside and outside of your home, so it’s important to choose the material that gives you the look you want. It’s also important to select the material that has the attributes you’re looking for. For example, metal window frames can conduct heat and cold, so they may not be as energy efficient as wood or vinyl windows. Additionally, some window frame materials can be painted to match your home’s exterior or interior, so that may be an important consideration.

Wood windows can be painted and stained. The downside to wood windows is that they must be regularly maintained. However, most wood windows are made from rot-resistant woods. When maintained correctly, they can last as long as metal windows.

Vinyl windows are inexpensive, energy efficient and durable. And while they cannot be painted, they come in a variety of colors and are virtually maintenance-free.

Steel windows are rarely used in residential buildings, as they aren’t as energy efficient as other types of windows and the window must be painted so they don’t rust.

Aluminum windows are strong and durable. They also allow for greater flexibility in window design. However, they aren’t as energy efficient as other types of windows.

Fiberglass windows are durable, efficient and strong. The frames can be painted to match any home. Because of their quality and durability, fiberglass windows are some of the more expensive widows on the market.

Composite windows have sashes and frames made from more than one type of material. This allows the manufacturer to customize the windows to fit the exact needs of the consumer. Some composite windows have a wood interior that can be painted with more efficient material such as vinyl or aluminum that better resists weather. New composite windows can be made from recycled wood and plastic that can be painted but resist rot.

Q: How do I know which kind of windows are the best choice for me?
A: Your local window contractor will help you decide which manufacturer, style and material of windows is the best fit for your budget, home and aesthetic preferences. It’s wise to make a list of what you’re looking for in new windows so that your window installer can help you decide which windows best fit your needs.

Q: How much do new windows cost?
A: The cost of new windows greatly varies based on the type of windows you select, the manufacturer and the number of windows you have installed. It also depends on whether you’re having replacement windows installed (windows that are custom ordered to fit in place of your existing windows) or whether you’re having new window frames and jambs installed as well. Your window contractor can provide an estimate based on your specific requirements.

Q: How long will it take to install new windows?
A: That depends on the size and scope of your job. A simple window installation may take an hour, while installing new windows throughout an entire home may take several days or a week. Your window contractor should be able to give you an estimated time frame on your specific project.

Q: Can I put in new windows myself?
A: Like with many home improvement projects, you can replace your windows yourself. However, for most window replacement jobs, it's better to hire a skilled professional. Professional window installers know the best materials and installation techniques for the job. And because they have so much experience removing old windows and installing new ones, they can do the job faster and much more effectively than can most homeowners.

Q: What about getting my new windows from a home improvement store?
A: Most home improvement stores sell new windows, and many advertise low prices. But you may sacrifice selection and quality by getting your new windows from a home improvement store. Most have a smaller selection, so you may not get the windows that best suit your home and your needs. And if they sell discount windows or off-brand products that are less expensive, you run a greater risk that the manufacturer will go out of business, leaving any warranties null and void. Another factor to consider is that most home improvement warehouses don’t provide installation or they rely on subcontractors. That means you can be caught between the retailer, the manufacturer and the installer if there are any problems with your windows.

Q: I’ve heard it’s important to hire a local window contractor that is an authorized installer. What does that mean and why should I look for a certified window installer?
A: Most major window manufacturers certify window contractors whom they have trained to install their specific products. These authorized installers also sell new windows and replacement windows. You’re likely to get a better installation, and some manufacturers even offer extended warranties on products their installers put in. And if something goes wrong later, you can avoid added hassle by hiring the same contractor for the purchase and installation of new windows one company will be responsible for the work.

Q: What happens if someone gets hurt while working on a job on my property?
A: When you hire a legitimate window contractor with the correct license, liability insurance and workers’ compensation insurance, you won’t have to worry. Under workers’ compensation insurance, every employee of the company is covered in the case of accident or injury. You will not be held responsible for damages. Make sure you ask your contractor to show you a copy of their active workers’ compensation policy.
